minute fulvous pile. Like the T. dbbreviatus and setosus, it seems 

 to be common in the laurel-regions of Gomera, where it was dis- 

 covered by Dr. Crotch and his brother during the summer of 1864. 

 It is also a very constant species, since out of 186 examples which 

 I have inspected carefully I can detect no appreciable deviation 

 from its type. 



Tarphius Wolffii, n. sp. 



T. parallelo-oblougus, piceus, setulis brevibus tectus ; prothorace 

 ante medium latiusculo, ad latera regulariter rotundato, utrinque 

 late explanato ; elytris postice truncate declivibus, grosse seriatim 

 punctatis, leviter nodosis (nodis subglabris, paulo rufescentiori- 

 bus) ; antennis pedibusque rufo-testaceis. Long, c.orp. lin. 2. 



Habitat Maderam australem, in castanetis editioribus supra urbem 

 Funchalensem a Dom. C. Wolff, M.D., nuper detectus. 



Obs. Species T. truncato affinis, sed differt corpore majore la- 

 tiore, prothorace pnesertim ampliore latiore ante medium multo 

 magis rotundato et utrinque latius explanato, elytris sensim minus 

 lateraliter compressis, in interstitiis alternis minus (sc. vix) elevatis 

 et in nodulis minus setosis. 



Two examples of this Tarphius have lately been communicated by 

 Dr. C. Wolff, an energetic Prussian coleopterist who has worked 

 carefully in the south of Madeira. They were captured by nim in 

 the chestnut- woods at " the Mount," in company with the equally 

 rare T. ruyosus ; and I have much pleasure in dedicating the species 

 to him. It is evidently much allied to the T. truncatus, with which 

 indeed in its colour and sculpture, as well as in the rather truncated 

 hinder region of its elytra, it agrees. It is, however, both larger 

 and relatively broader than that insect ; its prothorax especially is 

 wider and more developed, being much more rounded before the 

 middle and more broadly flattened towards the edges ; and its elytra 

 are less compressed laterally, with their alternate interstices less 

 evidently raised (indeed scarcely raised at all), and their nodules more 

 isolated and somewhat less setose. 



Genus PROSTHECA. 

 Wollaston, Ann. Nat. Hist. v. 254 (1860). 



Prostheca aspera. 



P. linearis, fusco-ferruginea, subopaca ; capite prothoraceque rugo- 

 sis. tuberculatis ac setulis paucis valde distantibus obsitis, hoc fere 

 sequali, postice angustiore, ad latera oblique recto, angulis anticis
